Automatic classroom roll-call system based on WIFI and intelligent mobile phones

Abstract

The invention discloses an automatic classroom roll-call system based on WIFI and intelligent mobile phones. The system is composed of an intelligent mobile phone roll-call master control terminal, a WIFI wireless router and intelligent mobile phone sign-in terminals. The intelligent mobile phone roll-call master control terminal is used for recording sign-in information of multiple intelligent mobile phone sign-in terminals. Students use the intelligent mobile phone sign-in terminals to complete sign-in. The intelligent mobile phone roll-call master control terminal and the intelligent mobile phone sign-in terminals are connected with the WIFI wireless router. The intelligent mobile phone sign-in terminals acquire the IP address and the used port number of the intelligent mobile phone roll-call master control terminal by a discovery message and a discovery response message, and then the intelligent mobile phone sign-in terminals complete sign-in through a sign-in message and a sign-in response message based on a fingerprint verification function and a TCP protocol so that the intelligent mobile phone roll-call master control terminal used by a teacher is enabled to rapidly collect the sign-in information of all the students, multiple times of automatic roll-call can be realized in the classroom, roll-call efficiency can be enhanced and teaching time can be saved.

Description

technical field [0001] The invention discloses an automatic classroom roll call system based on WIFI and a smart phone, belonging to the field of intelligent control of the Internet of Things. Background technique [0002] In the teaching process, the classroom roll call can prevent students from skipping classes, ensure students' study time in class, and guarantee the teaching effect to a certain extent. However, the traditional manual roll-calling method has the disadvantage of taking a long time, and it cannot spend a lot of time on roll-calling in each class. Therefore, the effect of naming will be greatly reduced. Existing attendance methods such as fingerprint check-in require a large amount of equipment to complete class attendance for universities with many classes, and the investment is relatively large. [0003] The classroom automatic roll call system based on WIFI and smart phones proposed by the present invention can make full use of the smart phones widely use...
